The purpose of this study was to analyze a causal relations of children's learned helplessness, stress, perception of self-competence and mother's childrearing attitudes. The subjects were 370 of 4th and 6th grade in elementary school and the second grade in junior high school in Busan and their's mothers. The instruments used for this study were learned helplessness scale, stress scale, self-perception profile for children, and childrearing attitude scale. The data was analyzed with pearson's correlation, multiple regression and path analysis. The major findings of this study were as follows : 1. Children's global self-worth, social self, age and mother's controlling childrearing attitudes predicted children's stress. 21% of the variance of children's stress was explained by these variables. 2. Children's stress, global self-worth, academic and social self predicted children's learned helplessness. 54% of the variance of children's learned helplessness was explained by these variables. 3. 1) Global self-worth was the first contribution and had a indirect effect through stress as well as a direct effect on children's learned helplessness. 2) Children's stress and academic self had direct effect on children's learned helplessness. 3) Children's social self had a indirect effect through stress as well as a direct effect on children's learned helplessness. 4) Mother's affectionate childrearing attitudes had indirect effect through academic, and social self and global self-worth on children's learned helplessness. Mother's controlling childrearing attitudes had indirect effect through stress on children's learned helplessness. Children's age had a indirect effect through global self-worth and stress and children's sex had a indirect effect through social self on children's learned helplessness.

The purpose of this study is to investigate children's emotional regulation and social competence in relation with peer friendliness. Specifically, it examined the hypotheses that children's emotion regulation strategies would be different depending on age, gender, and peer friendliness, and that children's emotion regulation strategies would affect their social competences. The subjects were 197 of the second, fourth, and sixth graders in an elementary school located in Gangdong-gu, Seoul. The findings are as follows: first, children's emotion regulation strategies are different according to gender and age. Girls use more 'external response strategy' than boys do. Elder children use more 'internal response strategy' than younger children, and younger children use more 'problem solving strategy' than elder children. Second, children's emotion regulation strategies are different depending on the degree of peer friendliness. Children employ more 'problem solving' and 'internal response' strategies to close friends rather than to just friends. Children used more the strategies as 'request for social support', 'evasion', and 'external response' to just friends rather than to close friends. Finally, children's social competencies are influenced by the strategies of 'problem solving' and 'evasion'.

The purpose of this study was to find out adolescents' and their mothers' responses to the minimum standard of age suggested by previous research not to share bedroom among parents and child, children of the opposite sex, or children of the same sex. The data from 310 pairs of junior school students and their mothers were analyzed. The results showed that the percentages of agreements to the suggested ages were not the same. Adolescents were in general more likely flexible to the minimum age than were their mothers. The age standard of the opposite sex children over 10 years old must not share a bedroom was the most agreeable both to child and mother. Both mother and adolescents' children were more likely flexible to the rule that parents should not should not share a bedroom with a child over age 5. However, they were serious about sharing a bedroom between same sex children regardless age. Further research should reveal precisely the age standard represent the high agreement among the family members.

Over the period between January 1997 and December 1998, herbal medicine was more than three times administered to the patients coming to Na dong gyu's Oriental Medical Clinic on account of the symptom of growth deficiency. According to radiological opinions about the patients providing cooperation for measuring their height and weight as well as their bone age every three months, it was found that the growth plates were not closed. A research was conducted for 200 children randomly selected of patients in prepuberty (they grew by less than 5cm a year before treatment at a age of 12years for female children and 14years for male children). As a result, the following conclusion was drawn: 1. The randomly selected subjects were made up of 116 male and 84 female children in terms of gender. The age direstribution was most 10 to 12 years in 86 children(34.00%), followed by 8-10 years(27.50%) and 12 to 14 years(19.50%). 2. Considering the distribution of sick children's parental height, the fathers of 141 children(70.50%) measured less than 170cm high, the subaverage height, while the mothers of 172 children(86%) measured less than 160cm high, the subaverage height. It was shown that sick childen's height was genetically influenced by their parents. 3. Children patients's weight at a time of birth was most 3.1-3.5kg for 85 children(44%) and less than 2.5kg which came under the range of growth dificiency for 19 children(9.5%). 4. The highest proportian of the children patients with growth dificiency(56.33%) had the symptom of digestive disorders, of which 77 children patients(18.78%) had anorexia, 16.59% of children patients had the high level of respiratory disorders. Both the digestive disorder and the respiratory disorder put together, they had the high rate of 72.92%. Therefore, this indicates that both the digestive disorder and the respiratory disorder have a great effect on children's growth dificiency. 10.74% of chilren patients were shown to have allergic disorders, which indicates that they also exert an effect on growth deficiency. Specifically, 7.07% of the children patients had the high level of obesity, which shows that an excessive uptake of nutrition may rather induce children to have growth dificiency though an appropriate amount of nutritional uptake is necessary. 5. Comparing their bone age and their chronological age, 58 children patients(29.00%) showed that they were the same at the highest percent. 79 children patients(39.50%) showed that thier bone age was lower than their chronological age. And 63 children patients(31.50%) showed that their bone age was higher than their chronological age. 6. As regards the prescription administered to children patients for treating their growth dificiency, Growth tang A related to the kidney, the congenital factor, of the causes for growth dificiency in traditional Oriental Medicine was administered to 108 children patients(54%), whereas the Growth tang B related to the spleen, the acquired factor, was administered to 92 children patients(46%). 7. 116 male children patients with growth dificiency had the average value of growth for one year before treatment, 4.39cm, while 84 female children patients had the average value of growth for one year before treatment, 4.24cm. A total of 200 children had the average value of growth for one year before treatment, 4.33cm. The annual average value of growth in growth curve surveyed by the Korea Pediatrics Society was 5.79cm. Compared to this value, the one year average value of growth for 108 male and female children patients taking Growth tang A was shown be 8.44cm, which indicates a greater growth by 4.12cm(95.37%) in comparison with the average value of growth before treatment, 4.32cm, and a greater growth by 2.65cm(45.77%) compared to 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society. Also, the average value of growth before treatment for 92 male and female children patients taking Growth tang B was shown to be 8.47cm, which indicates a greater increase by 4.15cm(96.06%) compared to 4.32cm, the average value of growth before treatment and a greater increase by 2.67cm(46.29%) in comparison with 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society. Considering the average value of growth for male and female children patients taking Growth tang A and B, it was shown to be 8.46cm, which indicates a greater increase by 4.14cm(95.81%) compared to 4.32cm, the average value of growth before treatment, and a greater increase by 2.67cm(46.11%) compared to 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society.

PURPOSE This study was intended to analyze the play-form of normal preschool children as related to age, sex, educational experience and social maturity. METHOD 1. Subjects The subjects of this study were eighty seven 3-, 4- and 5-year-old preschool children attending educational institutions in Seoul. 2. Instruments The instruments used in this study consisted of twenty one-minute observations in 5 preschool settings and a questionnaire designed to measure the children's social maturity filled in by their parents. The observations provided information on the children's free play, that is 1) play-form: solitary, parallel and group play 2) use/non-use of toys 3) behavior: play, activity, doing nothing, onlooking 4) stationary/moving dimensions 5) play group size The questionnaire measured such factors as communication, socialization, locomotion, self-help and self-direction. 3. Data Analysis Data analysis consisted of percentage and Chi square. RESULTS 1. Play-Form The relationship between age and play-form proved to be significant at the .05 level. That is, in both boys and girls, solitary play decreased with age and group play increased with age while parallel play maintained a similar position. The relationship between sex and play-form proved to be significant at the .05 level in 3-& 4-year-old children, but not significant in 5-year-old children. That is, in their $3^{rd}$ year boys engage in the solitary play more than girls and in their $4^{th}$ year boys engage in more group play than girls. 2. Toys Without differentiation of sex and age, cases of using toys in play exceed those cases where toys were not used. 3. Behavior The relationship between age and behavior proved to be significant at the .05 level in both boys and girls. That is, with increase of age, play decreased and activity increased in boys while play increased and doing nothing decreased in girls. 4. Moving Status Totally, moving occurred more frequently in play than stationary status. Moving proved not to have a significant relationship with age, but it did Navel a significant relationship with sex at the .05 level. That is, moving tended to increase with the increase in age in both boys and girls, but not at a significant level. Boys moved significantly more than girls in all three age levels. 5. The Relationship between Educational Experience and Play-Form There was a tendency for children with longer preschool experience to engage in less solitary play and more group play than children who had less than one semester of preschool experience, but this difference was not statistically significant. 6. The Relationship between Social Maturity and Play-Form The high social maturity group engaged in less solitary play and more group play than the low social maturity group, but this was not a statistically significant difference. 7. Play Group Size Play group size was 2~10 children, but the majority of play groups consisted of 2~3 children. There was a tendency for play groups composed of 2 children to decrease with age and play groups composed of 3 children to increase with age. No significant difference was found between the sexes in play group size.

This research was performed to screen eye health status for pre-school children (4~5 age) and establish as eye health checking system m community health center. This data was collected from 1st February, 1995 to 31st October, 1995. To screen the state of their vision, the Developed Visuual Test (D.V.T) was used for pre-school children. This is used at home by their parents and then it is also used among the kindergarten health team at Jung-gu health center in Seoul. This was done with the and of Randot and Han Choun Souk tests. The total number of children who were tested was 1441. Among the children, children aged 5 were 707, and those aged 4 were 734. The results of this study were as follows; * Description of the health status for the pre-school children. 1. The rate of children average vision in both eyes, whose was below 05 by Han Choun Souk are 7.6% (age 4) and 4.8% (age 5). 2. Only 20 4% (age 5) and 30 8% (age 4) of the pre-school children had been tested through the ophthalmic department. 3. The children with a level below 05 (Han Choun Souk test) had been tested only 43% (age 4), and 12% (age 5) 4. There was no particular difficulty in understanding the D.Y.T: 13.9% (age 4), 11.6% (age 5) of the tested children had eye problems. 5. 231 cases were trichiasis, entropin, strabismus, and amblyopia. * The different visual tests. The results of the visual tests between the two groups (parents and health teams) are similar and it shows that parents can easily test at home. * Delivery system of the D.V.T questionnaire The way children's parents received the D.V.T questionnaire were carried out by two ways By mall from the community health center. Send through the institution, for example the kindergarten school The receipt rate of this D.V.T questionnaire sent through the institution was higher than sent by mall.

Objectives: The objective of this study is to examine the association between the children's psychopathology and age, intellectual quotient, and parental psychopathology in children with post-traumatic stress disorder (PTSD). Methods: The emotional and behavioral problems of 35 children with PTSD (23 boys, 12 girls, mean age, $10.26{\pm}2.47$ years) were investigated by retrospective chart review. Their parents' anxiety and depression symptoms were also investigated. We examined the correlations between children's psychopathology and their parents' anxiety and depression symptoms, as well as their age and IQ. Results: There were positive correlations between maternal trait anxiety and depression, and children's emotional problems. State and trait anxiety of children with PTSD were positively correlated with age, and attention-deficit hyperactivity disorder symptoms were negatively correlated with age. Conclusion: Our results suggest that psychiatric manifestation of children who experienced trauma could differ according to the development stage, and the treatment of children with PTSD should involve parental education about the effect of maternal emotional states on children.

The purpose of this study was to explore musical development of 3- to S-year-old children and their musical home environment. The subjects were one hundred ninety-four children and their mothers enrolled in four kindergartens in Seoul. Each child sang the birthday song with peers in a birthday play setting. It was audiotaped for the children to sing the song. Questionnaire of musical home environment developed by the researchers was used for the mothers. The children's rhythm and pitch development were coded by the scoring categories of Project Spectrum(Krechevsky, 1994). The data were analyzed by t-test, ANOVA, Scheffe, and Pearson correlation. The results of this study were as follows: Firstly, there was no a significant difference in the children's rhythm development among three age-groups as well as between boys and girls. Among rhythm subcategories, the unit of note was ranked in the highest score and the pulse the next. Secondly, there were significant differences in children's pitch development among three age-groups and between boys and girls. The older children significantly achieved higher scores than the younger. Among pitch subcategories, the contour was ranked in the highest score and the interval the next. Thirdly, the children's musical development and their physical home environment related to music were correlated positively. The children's pitch development was significantly related to the mothers' musical attitude and the children's rhythm development to the mothers' educational levels.

The purpose of this study was to examine children's self-regulation and their problem behavior according to family interaction types. The subjects were 227 children and their mothers, and 14 teachers in Jeonbuk. To obtain family interaction types, self-questionnaires of FACES III are given to mothers. Also, self-questionnaires of children's self-regulation and problem behavior were given to teachers. The data were analyzed by computing t-test, ANOVA, Duncan post test, and multiple liner regression. The results were as follows. First, There was a difference in the children's self regulation and problem behavior, but not in family cohesion and adaptability, according to the children's sex, age, and family variables. Second, it was found that there was a difference in self-regulation and problem behavior according to family interaction types. It showed that self-regulation was higher and problem behavior was lower in the most 'enmeshed' families in cohesion and the most 'chaotic' families in adaptability. Third, considering the relative strength of each variable on children's problem behavior, it was shown that children's sex and age had the greatest influence on problem behavior, followed by self-regulation and family's cohesion. In conclusion, it is suggested that the efforts to improve family cohesion as a psychological environment should be made in order to increase the children's self regulation and to decrease the children's problem behavior.
